CROSS-REFERENCE AND PRIORITY CLAIM TO RELATED PATENT APPLICATION

This application claims priority to U.S. provisional patent application Ser. No. 62/750,560, filed Oct. 25, 2018, and entitled “Proxy Nodes for Expanding the Functionality of Nodes in a Wirelessly Connected Environment”, the entire disclosure of which is incorporated herein by reference.

INTRODUCTION

Examples of systems where wireless nodes are arranged in a wirelessly connected environment to support a variety of remote management operations, including location tracking, status monitoring, and remote control with respect to devices in environment such as retail stores are described in US Pat. App. Pubs. 2017/0164314, 2018/0007648, 2018/0288720, 2018/0288721, and 2018/0288722, the entire disclosures of each of which are incorporated herein by reference. As described in these references and below, the wireless nodes can be deployed in environments such as a retail store and provide remote management and control over any combination of product display assemblies, locks, power strips, display shelves, display hooks, and other node types.

However, even with a flexible and powerful wireless environment as described in these examples, it may be the case that some of the devices corresponding to the various types of wireless nodes lack native functionality that is later desired for such devices. For example, a product display assembly and/or lock in the wireless network may be configured with circuitry for reading a first type of user credentials from a user in order to support a decision as to whether the user is authorized to perform an action such as arming and/or disarming the product display assembly or locking and/or unlocking the lock. However, the existing circuitry of the product display assembly or lock may not support reading a second type of user credentials. Rather than forcing a hardware retrofit of the product display assembly or lock to enable it to read the second type of user credentials (which may be challenging and costly), the inventor discloses that one or more proxy nodes can be added to the wireless network to upgrade one or more of the devices on the wireless network via a proxy function.

Toward this end, as an example embodiment, disclosed herein is an apparatus comprising a proxy node for association with a wireless node in a wireless network that includes a plurality of wireless nodes, wherein the proxy node comprises (1) a wireless transceiver for wireless communication over the wireless network and (2) a circuit that provides a circuit function, and wherein the proxy node is configured to wirelessly communicate over the wireless network with the associated wireless node to make the circuit function available to the associated wireless node via proxy.

In another example embodiment, disclosed herein is a system comprising (1) a plurality of wireless nodes arranged as a wireless network, wherein each of a plurality of the wireless nodes includes a wireless transceiver for wireless communication over the wireless network, (2) a computer system configured for wireless communication with the wireless network to communicate with and manage the wireless nodes, and (3) a proxy node for association with a wireless node in the wireless network, wherein the proxy node comprises (i) a wireless transceiver for wireless communication over the wireless network and (ii) a circuit that provides a circuit function, and wherein the proxy node is configured to wirelessly communicate over the wireless network with the associated wireless node to make the circuit function available to the associated wireless node via proxy.

In another example embodiment, a method is disclosed tor expanding a functionality of a wireless node on a wireless network that includes a plurality of wireless nodes, the method comprising (1) connecting a proxy node to the wireless network, wherein the proxy node includes a circuit that provides a circuit function, (2) associating the proxy node with a wireless node of the wireless network, (3) wirelessly linking the proxy node with the associated wireless node over the wireless network, and (4) through the wireless linking, making the circuit function available to the associated wireless node via proxy.

Any of a number of circuit functions can be made available to wireless nodes in the wireless environment via proxy.

For example, a reader circuit can be provided via the proxy node, where the reader circuit operates to read user authorization credentials from a user. As an example, the reader circuit can be a radio frequency identification (RFID) reader circuit that is able to read an RFID card presented by a user.

As another example, a sounder circuit can be provided via the proxy node. As an example, it may be desirable for a wireless node on the wireless network to be upgraded with a higher power sound alarm. Rather that physically retrofit such a wireless node, a sounder circuit with a higher decibel alarm could be added via proxy through the proxy node.

As another example, a visual indicator circuit can be provided via the proxy node. As an example, wireless nodes can be augmented to provided visual outputs, such as visual outputs about their operational statuses, via one or more light emitting diodes (LEDs) that are provided via the proxy node. As another example, more sophisticated visual outputs could be supported by the proxy node, such as display screens. Further still, forms of output other than sound and visuals could be provided via the proxy node—e.g., a haptic circuit could be included as part of the proxy node to provide a haptic output function by proxy to a wireless node.

As yet another example, a sensor circuit can be provided via the proxy node. Any of a number of different types of sensors could be supported by the proxy node, including but not limited to microphones, light sensors, motion detectors, acceleration sensors, temperature sensors, touch sensors, pressure sensors, voltage sensors, power sensors, and/or current sensors.

A data structure such as an association table can be maintained within the system to define the wireless node(s) with which a given proxy node is associated. This data structure can thus define a soft and dynamic set of associations between proxy nodes and wireless nodes, where a proxy node can be associated with a wireless node as a 1:1 relationship or where a proxy node can be associated with multiple wireless nodes as a 1:many relationship. In an example embodiment where a given proxy node is associated with multiple wireless nodes in a 1:many relationship, the capabilities of the system are further expanded in that users can be permitted to perform a single action on the subject proxy node to affect multiple wireless nodes. For example, if there are multiple product display assemblies linked to a given proxy node, and the proxy node is being used to provide an RFID card reading function to the linked product display assemblies, a user can thus be permitted to arm or disarm multiple product display assemblies with a single card swipe at the proxy node (rather than having the user swipe in at each product display assembly individually). Similar benefits could be provided with wireless nodes that correspond to locks and other node types.

The proxy nodes as described herein can be used to augment any of a number of different types of wireless nodes that may be present within the subject wireless network, including but not limited to product display assembly node types, display shelf node types, a display hook node types, lock node types, power outlet node types, power strip node types, audio/video controller node types, camera node types, sensor node types, status indicator node types, docking station node types, and/or goods node types.

Further still, the proxy node can include an interface circuit for connection with devices that are not otherwise on the subject wireless network to provide a proxy service for bridging such devices onto the wireless network. Such an arrangement can help extend the wireless network to include devices that may be provided by third parties.

These and other features and advantages of the present invention will be described hereinafter to those having ordinary skill in the art.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS

FIG. 1 shows an example system 100 that can serve as a connected environment of wireless nodes 102. Each wireless node 102 may include a wireless transceiver that allows for the formation of wireless network 104 through which the wireless nodes 102 can communicate with a remote computer system such as gateway computer 110. Each wireless node 102 may also have an associated node identifier (Node ID) that serves to identify that wireless node 102 within system 100. Any of a number of types of identifiers can be used as Node IDs, such as network addresses or MAC addresses used for communicating with particular wireless nodes 102 within the system, or other unique identifiers that may be tied to wireless nodes 102 (e.g., serial numbers, etc.). Each wireless node 102 may also be configured to communicate with other wireless nodes 102 within the wireless network 104. As an example, the wireless network 104 may be configured as a wireless mesh network which can provide robust and reliable communication pathways from wireless nodes 102 not only to the gateway computer 110 but also to each other and through each other to gateway computer 110, which can be highly advantageous when the wireless nodes 102 are located in noisy environments that may include various forms of potential signal interference. For example, the system 100 may be deployed in a number of noisy environments, an example of which is a retail store such as an electronics retail store. The presence of large number of customers in the retail store (where each customer will likely be carrying his or her own wireless device such as a smart phone) in combination with the large number of electronic products in the retail store can be expected to create a noisy signal environment, and the configuration of wireless network 104 as a wireless mesh network can help prevent data communication losses between the wireless nodes 102 and gateway computer 110. Also, the wireless network 104 may rely on any of a number of wireless communication technologies. For example, the wireless network 104 could be a local Wi-Fi network. As another example, the wireless network 104 could be a wireless network that uses Bluetooth, BTLE, or other networking techniques (e.g, Zigbee).

Continuing with the retail store environment example, the wireless nodes 102 may correspond to one or more types of devices that are located throughout the store. For example, one or more of the wireless nodes 102 may be included as part of or operatively coupled with one or more of the following types of devices: a product display assembly, a display shelf, a display hook (e.g., a peg hook), a lock (which may regulate access to doors or the like for enclosed spaces such as cabinets, rooms, etc.), a power outlet, a power strip, an audio/video controller, a camera, a sensor, a status indicator, a docking station (e.g., a docking system for a portable computing device such as a tablet computer), goods, etc.

Gateway computer 110 can serve as a hub for collecting data from and sending data to the wireless nodes 102. The data sent from gateway computer 110 to a wireless node can include command data for managing and controlling a wireless node, examples of which are discussed below. The gateway computer 110 can also communicate over a network 112 with a remote computer system such as server 120 via a communication protocol such as RS-232 (although it should be understood that alternative communication protocols could be employed). In this fashion, server 120 can further connect the wireless nodes 102 with other remote computers via wide area networks such as the Internet.

A management user interface 130 can interact with the gateway computer 110 and/or server 120 to provide users with access to data from the wireless nodes 102 as well as control over the wireless nodes 102. The management user interface 130 can be executed by a computer that is in communication with the gateway computer 110 via a network connection 124 and/or server 120 via a network connection 122 (where such a computer could take the form of a tablet computer, a smart phone, or other forms such as laptop computers, desktop computers, etc.). Network connections 122 and 124 can be any suitable network connection for connecting the management user interface 130 with the server 120 and/or gateway (e.g., a WiFi connection, an Ethernet connection, etc.). However, it should be understood that management user interface 130 could also be executed by the gateway computer 110 and/or server 120 themselves.

Server 120 can be connected with a number of different wireless networks 104 that are spread over different locations, such as a wide geographic area. Continuing with the retail store environment example from above, different retail stores can have their own wireless networks 104, and these different wireless networks 104 can be communicatively coupled with a common server 120 (where it should be understood that the common server 120 may include a network of servers, such as in a cloud service arrangement). In this fashion, server 120 can aggregate data collected from wireless nodes 102 in a number of different retail stores. Further still, the server 120 can make such aggregated data available to remote users via the management user interface 130 that is linked into the server 120 via a network connection 122. In this fashion, a user of the management user interface 130 can remotely monitor and control wireless nodes that are spread across a number of different retail stores.

Additional details about example embodiments of the wirelessly connected environment of system 100 can be found in the above-referenced and incorporated US Pat App Pub 2017/0164314. For example, while a retail store environment is discussed herein as an example, it should be understood that the system 100 of FIG. 1 could be deployed in other environments as well, as discussed in US Pat App Pub 2017/0164314.

FIG. 2 shows an example embodiment where the system 100 where the wireless nodes 102 correspond to a plurality of different product display assemblies 202. The product display assemblies 202 can be configured to secure and display products for presentation to consumers. As examples, such products can be electronic devices 206 (e.g., smart phones, tablet computers, smart watches, cameras, etc.). In the example of FIG. 2, the product display assemblies 202 can be arranged as a wireless mesh network via wireless links 204. The product display assemblies 202 can also wirelessly communicate with the gateway computer 110 via the wireless mesh network, and the gateway computer 110 can communicate over network 112 with server 120. Through these connections, the server 120 can collect data from the various product display assemblies 202 and make such data available to remote users via the management user interface 130 linked into the server 120 via a network connection 122. However, as noted above in connection with FIG. 1, the management user interface 130 may also or alternatively link into gateway computer 110 via network connection 124.

FIGS. 3A and 3B show an example embodiment of a product display assembly 202 that includes a puck assembly 302 and a base assembly 304. Tether 310 connects the puck assembly 302 with base assembly 304. While the ensuing examples will discuss a product display assembly 202 configured as a wireless node 102 where the product display assembly 202 includes a puck assembly 302 and base assembly 304, it should be understood that other types of product display assemblies could be employed as wireless nodes 102 within system 100 (e.g., a product display assembly that may include only a puck assembly 302 or other singular component for displaying a product to a customer).

An electronic device can be mounted on surface 306 of the puck assembly 302 so that the electronic device can be securely displayed to customers in a store. The puck assembly 302 is moveable between a rest position and a lift position. When in the rest position, the puck assembly 302 contacts the base assembly 304, as shown in FIG. 3A. Power can be provided to the base assembly 304 via input power line 320, and this power can be distributed to the puck assembly 302. When in the lift position, the puck assembly 302 separates from the base assembly 304, as shown by FIG. 3B. FIG. 3B also shows how the tether 310 remains connected to the puck assembly 302 and the base assembly 304 when the puck assembly 302 is in the lift position. This allows for a customer to pick up, hold, and inspect the electronic device when making a purchase decision. To provide ease of handling, tether 310 may be a retractable tether. However, it should also be noted that some practitioners may choose to omit the tether 310 from the product display assembly 202, in which case the puck assembly 302 would be completely separated from the base assembly 304 when the puck assembly is in the lift position.

Examples of product display assemblies 202 that can be adapted for use in the practice of the embodiments described herein are disclosed in U.S. Pat. Nos. 8,558,688, 8,698,617, 8,698,618, and 9,786,140; and U.S. Patent Application Publication Nos. 201410159898, 201710032636, 2017/0164314, and 2017/0300721, the entire disclosures of each of which are incorporated herein by reference.

For example, FIGS. 5A and 5B reproduce FIGS. 27 and 28 from the incorporated '140 patent and show an example product display assembly 202 that is further described in the '140 patent. The product display assembly 202 shown by FIGS. 5A and 5B includes a puck assembly 302 and a base assembly 304. An electronic device 206 can be mounted on and electrically connected to the puck assembly 302, and the puck assembly 302 can be moved between (1) a rest position where the puck assembly 302 rests on the base assembly 304 (see FIG. 5A) and (2) a lift position where the puck assembly 302 does not rest on the base assembly 304 (see FIG. 5B). As noted, the product display assembly 202 may optionally include a tether assembly 310 that keeps the puck assembly 302 connected to the base assembly 304 even when the puck assembly 302 is in the lift position. A power cable 512 provides an electrical connection between the puck assembly 302 and an electronic device 206 for display through which the electronic device 206 can be charged. The puck assembly 302 can receive power from a power source via the base assembly 304 when the puck assembly is at rest. Electrical contacts included on the puck assembly 302 and base assembly 304 can contact each other when the puck assembly 302 is at rest, thereby forming an electrical connection through which power can be delivered from a power source (not shown) to the puck assembly 302 via the base assembly 304 and the electrical connection formed by the contacts. When the puck assembly 302 is lifted, the contacts lose contact with each other, thereby breaking the electrical connection.

FIG. 3C shows an example where the product display assembly 202 is configured as a wireless node 102 by including a wireless transceiver in the puck assembly 202, to thereby permit the puck assembly 302 to send and receive wireless signals 350 via wireless network 104. FIG. 3D shows another example where the product display assembly 202 is configured as a wireless node 102 by including a wireless transceiver in the base assembly 304, to thereby permit the base assembly 304 to send and receive wireless signals 350 via wireless network 104. Furthermore, if desired by a practitioner, wireless transceivers may optionally be included in both the puck assembly 302 and the base assembly 304 to allow both the puck assembly 302 and base assembly 304 to communicate wirelessly with remote devices.

Through their status as wireless nodes 102, the product display assemblies 202 can provide location-awareness for the system 100 with respect which product display assemblies are where and what products they are displaying. However, establishing location-awareness can be a challenge. Base assemblies 304 are typically fixedly secured to surfaces such as counters and walls in a retail store, and the locations of these fixtures can be referred to as post positions. The fixed nature of securing base assemblies 304 to counters or walls makes moving base assemblies 304 to new post positions inconvenient, time-consuming, and labor-intensive. Moreover, with many product display assemblies 202, the puck assemblies 302 can be detachable from the base assembly 304 and/or tether 310 to allow for swapping out puck assemblies 302 and/or their attached electronic devices 206 to new post positions. Given the potential for movement of puck assemblies 302 and/or electronic devices 206 to new post positions, remote location-aware tracking of electronic devices 206 can be a technical challenge.

In this regard, it is highly desirable to remotely track the precise location of products such as electronic devices 206 in a retail store, and more specifically to know which electronic devices 206 are being displayed at which post positions. Merchandisers typically devise detailed planograms (POGs) that will define which types of electronic devices 206 should be displayed at particular post positions in a retail store to achieve desired retail merchandising goals. For example, a merchandiser may want the newest and most expensive model of a particular brand of smart phone displayed at post positions 1-4 (which are expected to experience the most customer traffic), while older or less expensive models of a smart phone are to be displayed at post positions 5-8 (which are expected to experience less customer traffic). Monitoring planogram compliance can be a major burden at retail stores, and it is believed that example embodiments of the system 100 described herein can help facilitate effective remote monitoring of planogram compliance by providing an effective mechanism by which identifiers for electronic devices 206, puck assemblies 302, and base assemblies 304 can be tracked and linked with post positions.

FIGS. 4A-4D show example process flows that leverage the wireless communication capabilities of a product display assembly 202 to provide location-awareness for the system 100 regarding where puck assemblies 302 and electronic devices 206 are located relative to known locations such as post positions. As mentioned above, because base assemblies 304 are expected to be relatively fixed in terms of their locations in retail stores, while puck assemblies 302 and electronic devices 206 may change their locations in the retail store fairly often, the process flows of FIGS. 4A-4D provide practitioners with opportunities for improved location tracking of electronic devices 206 and assessing planogram compliance. FIGS. 4A and 4B show examples where the puck assembly 302 is configured to wirelessly communicate with a remote computer system such as gateway computer 110, while FIGS. 4C and 4D show examples where the base assembly 304 is configured to wirelessly communicate with a remote computer system such as gateway computer 110.

As shown by FIG. 4A, a remote computer system such as gateway computer 110 and/or server 120 can maintain a data structure 420 such as a table that associates identifiers for the base assemblies 304 (e.g., Base IDs) with locations in a store (e.g., post positions) The post positions can be known locations within a planogram for a store, and these locations can be defined with respect to frames of reference defined by a planogram in any of a number of manners. For example, in some instances, a planogram could define post positions in a relative manner that is not true to scale with respect to the spatial geometry of a store (e.g., Post Position 1 is the front row leftmost position on a defined table, Post Position 2 is the front row, second from the left position on the defined table, . . . , Post Position N is the back row, rightmost position on the defined table, etc.). However, other stores may define planograms in a more scaled manner where the post positions are represented with more geographical precision. However, the post positions need not be defined with the precision of GPS coordinates or the like unless desired by a practitioner.

Base assembly 304 can be configured with an identifier that serves to uniquely identify that base assembly 304 within system 100. For example, a different serial number can be assigned to each base assembly and stored in a memory as a Base ID that is accessible to circuitry in the base assembly 304. For example, a microprocessor that can be included as part of the base assembly 304 can come from the factory with a globally unique identification number that is similar in nature to a serial number. This identifier can be etched into the internal memory space of the microprocessor and available for reading out and referencing. Such an identifier can be used as the Base ID in an example embodiment.

The associational data in data structure 420 can be created and stored in the system 100 when base assemblies 304 are installed in a store. Registration can be carried out as a set up operation in software. Uncorrelated positions (e.g., base assemblies that do not have known post positions) can be placed on a software-defined planogram, and then each of these uncorrelated positions can be registered with a post position using a set up process. As base assemblies 304 (or product display assemblies 202 that include puck assemblies 302 and base assemblies 304) start coming online with gateway computer 110, the gateway computer will start seeing data that represents Base IDs (or pairings between Base IDs and identifiers for puck assemblies 302 (Puck IDs)). The gateway computer 110 can then issue wireless commands that correspond to “identify” requests to each of the uncorrelated product display assemblies 202 that will cause a status indicator such as an LED on the subject product display assembly 202 to identify itself (e.g., blink in a certain way). This identification can allow a user to physically identify a given base assembly 304 at a given post position with the uncorrelated Base ID data received by the gateway computer 110, which allows the system to register a given base assembly 304 with a given post position in data structure 420. In another example registration process, post positions can be manually labeled with respective codes or other unique identifiers and base assemblies 304 can be manually labeled with their Base IDs, and a user can manually enter a pairing between these values in the system to create data structure 420.

Once a Base ID has been associated with a post position, the system next needs to learn which puck assembly 302 and/or electronic device 206 is located at that post position. FIG. 4A shows an example process flow for this.

At step 400, the base assembly 304 sends its Base ID to the puck assembly 302. This communication can be accomplished via any of a number of techniques, including data transfers via the electrical signal passed through contacts or wireless transfers if both the puck assembly 302 and base assembly 304 are configured for wireless communication with each other. At step 402, the puck assembly 302 receives this Base ID from the base assembly 304. The puck assembly 302 can also read an identifier for the electronic device 206 (Device ID) that is connected to the puck assembly 302 (step 404). For example, with reference to FIGS. 5A and 5B, this determination can be made by reading data about the electronic device 206 through cable 512. Through this cable 512, the electronic device 206 can provide its Device ID to the puck assembly 302, and this Device ID can identify a make and model for the electronic device (e.g., an Apple iPhone X) as well as a serial number. For example, identifying information about the device 206 can be made available to the puck assembly 302 via a USB interface connection through cable 512. For example, upon connection via cable 512, a device 206 that is a USB device can output data that includes USB device descriptors. Identifying information that can include device type data and a Device ID can be determined from such descriptors. For example, the puck assembly 302 or gateway computer 110 can use base level descriptors that are broadcast in response to connection and also implement USB classes to query the device further e.g., USB image class, USB mass storage device class, etc.).

Receipt of the Device ID allows the puck assembly 302 to pair the Base ID with the Device ID, and this pairing of Base ID with Device ID can be wirelessly sent from the puck assembly 302 to the remote computer system at step 406. The puck assembly 302 may also send its own puck assembly identifier (Puck ID) to the remote computer system at step 406, which would pair the Base ID with the Device ID and the Puck ID. At step 408, the remote computer system receives this pairing of Base ID with Device ID (or Base ID with Device ID and Puck ID), and it updates the data structure to associate the Device ID (or Device ID and Puck ID) with a post position by virtue of the shared Base ID (see data structure 422). Thus, it can be seen that data structure 422 tracks which electronic devices 206 are at which post positions, and it can also track which puck assemblies 302 are at which post positions.

The example of FIG. 4B shows an example where the puck assembly 302 initiates the location-aware pairing operation. At step 430, the puck assembly 302 detects a trigger event, and this trigger event causes the puck assembly 302 to send a request for the base assembly's identifier (Base ID) to the base assembly 304 (step 432). This communication can occur over a similar channel as described in connection with step 400 of FIG. 4A. At step 434, the base assembly 304 receives the ID request and returns the Base ID to the puck assembly 302 (step 400 as described in connection with FIG. 4A). The remaining steps 402, 404, 406, and 408 can be performed as described above in connection with FIG. 4A.

Any of a number of trigger events can be used at step 430 to initiate the operation of pairing the Base ID with the Device ID and/or Puck ID. For example, the trigger event can be anytime that the puck assembly 302 detects a detachment from the base assembly 304 and/or tether 310 (which may indicate movement of the puck assembly 302 to a new post position, in which case the need for re-pairing may arise). The trigger event can also a detection by the puck assembly 302 that it has lost power. Another example of a trigger event can be the detection of a new connection with an electronic device 206 (e.g., via cable 512). Yet another example of a trigger event can be a detection that the puck assembly 302 has been lifted. Yet another example of a trigger event can be an expiration of a timer (which would define a timed basis for triggering the pairing operation so that the system can regular re-pair and confirm which electronic devices 206 are at which post positions). Yet another example of a trigger event can be a command sent from the computer system 110/120 in response to a user request through interface 130 to force a re-pairing.

As mentioned above, FIGS. 4C and 4D show examples where the base assembly 304 is configured to wirelessly communicate with the remote computer system. The example of FIG. 4C can begin at step 4500 with the puck assembly 302 reading the Device ID for its connected electronic device 206 (where this step can be performed in a similar fashion as step 404 from FIGS. 4A and 4B). At step 452, the puck assembly 302 sends the Device ID (or the Device ID paired with the Puck ID) to the base assembly 304. This communication can occur over a similar channel as described in connection with step 400 of FIG. 4A. At step 454, the base assembly 304 receives the Device ID (or the Device ID paired with the Puck ID). Then, at step 406, the base assembly 304 reads its Base ID and sends a pairing of the Base ID with the Device ID (or a pairing of the Base ID with the Device ID and Puck ID) to the remote computer system using its wireless communication capability. At step 458, the remote computer system receives this pairing of Base ID with Device ID (or Base ID with Device ID and Puck ID), and it updates the data structure 420 to associate the Device ID (or Device ID and Puck ID) with a post position by virtue of the shared Base ID (see data structure 422).

The example of FIG. 4D shows an example where the puck assembly's detection of a trigger event at step 470 initiates the pairing operation. The trigger event(s) used at step 470 can be the same as those discussed above in connection with step 430 of FIG. 4B.

Thus, as the process flows of FIGS. 4A, 4B, 4C, and/or 4D are repeated for different product display assemblies 202 in a retail store (or in multiple retail stores), the data structure 422 can allow for highly detailed planogram monitoring in real-time and around the clock, both on a per-retail store basis and on a multi-retail store basis. For example, a software application run by the remote computer system can compare data structure 422 with a planogram. In response to the comparison, the software application can determine whether at least one of the electronic devices 206 is located in an incorrect location. If so, the software application can generate a notification about the incorrect location, and this notification can be delivered to interested parties, such as personnel in the retail store who can move the electronic device to the correct location. Retail store personnel can receive such notifications on their smart phones and/or tablet computers (e.g., via the management user interface 130).

Further still, as customers interact with the product display assembly (such as by lifting a puck assembly 302 to inspect an electronic device 206), these actions can be detected and tracked by the product display assembly 202 and reported to the remote computer system using the techniques described in the above-referenced and incorporated '140 patent. As explained in the above-referenced and incorporated patents and patent applications, circuitry in the puck assembly 302 can be used to detect events such as lifts of the puck assembly. With these prior system designs, data about lift events could be communicated wirelessly via the puck (e.g., via a wireless transmitter in the puck or by using the tether 210 as an RF antenna). Alternately, such data could be communicated over a conductor within the tether 210 itself as a standard signal using the conventional RF signal approaches. The remote computer system can then correlate this lift tracking data with the data structure 422 to reliably know precisely which electronic devices are being inspected at which post positions.

The wireless communication capabilities of the product display assembly 202 can also be used to report other types of information to a remote computer system such as gateway computer 110 and/or server 120. For example, the product display assembly can wirelessly communicate access log data to the gateway computer 110 and/or server 120. The product display assemblies 202 can be designed so that only authorized users are allowed to arm and/or disarm the security features of the product display assemblies 202. Thus, if the product display assembly 202 is in an armed state, a removal of the displayed product (e.g., electronic device 206) can trigger an alarm. However, if the product display assembly 202 is in a disarmed state, the product can be removed from the puck assembly 302 without triggering an alarm. Accordingly, the product display assembly 202 can be controllable so that only authorized users are able to disarm (and arm) the product display assembly 202. Examples of technology that can be used to perform user authorization and authentication are described in U.S. Pat. No. 9,892,604 and U.S. Pat. App. Pub. 2017/0300721, the entire disclosures of which are incorporated herein by reference. The access log data can identify when a given product display assembly was armed/disarmed and by which authorized user. Furthermore, the access log data can also identify the electronic device 206 on display when an arm/disarm event occurred as well as where the product display assembly 202 was located when the arm/disarm event occurred (or the access log data can be correlated with data structure 422 to determine such information). FIG. 6 depicts an example process flow for use by the product display assembly 202 to log access data and report the access data to a remote computer system such as gateway computer 110 and/or server 120.

At step 600, an authorized user who attempts to arm/disarm a product display assembly (PDA) 202 is authenticated. As noted above, U.S. Pat. No. 9,892,604 and U.S. Pat. App. Pub. 2017/0300721 describe technology that can be used to authorize and authenticate users for such tasks. In response to authentication of the authorized user, the PDA 202 can be armed/disarmed as requested. At step 604, the PDA 202 logs event data relating to this arming/disarming. The event data that is logged may include an identifier for the authorized user who was authenticated at step 600 (e.g., each authorized user can be assigned a security fob or the like that includes a unique identifier associated with the user—such an identifier can serve as a User ID, and the authentication process can authenticate the user on the basis of this User ID). The event data may also include an identifier for the PDA 202, which can be referred to as a node identifier (Node ID) given that the PDA 202 in this example is serving as a wireless node 102 within system 100. The Node ID can be a Puck ID, Base ID, or other identifier that serves to uniquely identify a PDA 202 within system 100 (e.g., a combination of Puck ID and Base ID). Further still, the event data may also include an identifier for the product displayed by the PDA 202 (e.g., Device ID), as well as a timestamp for the event (e.g., date and time) and identifier for event type (e.g., arm event, disarm event, etc.). At step 606, the PDA 202 can wirelessly send the logged event data to the remote computer system via wireless network 104.

While the examples of FIGS. 2-4 and 6 describe various operations that can be performed with respect to wireless nodes 102 that correspond to product display assemblies 202, it should be understood that the features of FIGS. 2-4 and 6 could also be performed in connection with any of the other types of wireless nodes 102 within system 100 that are referenced above.

For example, the wireless nodes 102 can correspond to different locks within a retail store. Location awareness operations similar to those described by FIGS. 4A-4D can be performed to track where a given lock is being used. For example, a lock that regulates access to a cabinet can have a unique identifier that is associated with a cabinet location, and to the extent that the locks might be moved to different electronically identifiable cabinets, the FIGS. 4A-4D process flows can be used to pair Lock IDs with Cabinet IDs or the like. An example of an electronically controllable lock that can be configured with a wireless transceiver to serve as a wireless node 102 is described in US Pat. App. Pub. 2015:0048625, which is incorporated herein by reference. Further still, the lock could also be configured with an RFID reader or other sensor that would be capable of detecting RFID-equipped (or other sensible) products being moved into or out of an enclosure such as a cabinet secured by the lock to detect identifiers for such products. Such Product IDs could then be paired with the Lock IDs to track which products are secured by which locks. Also, a process flow similar to that of FIG. 6 can be performed by the lock to log events such as lock/unlock commands from authorized users and then wirelessly share the event log data with a remote computer system such as gateway computer 110 and/or server 120.

As another example, the wireless nodes 102 can correspond to different power strips within a retail store. Location awareness operations similar to those described by FIGS. 4A-4D can be performed to track where a given power strip is being used and whether any products are connected to the power strip. For example, a power strip that is used to power one or more electrical appliances (which may include one or more electronic devices 206) can have a unique identifier (e.g., Strip ID) that is associated with a location in a store, and to the extent that the power strips might be moved to different store locations, the FIGS. 4A-4D process flows can be used to pair Strip IDs with new locations. The power strip can also be configured to provide security functions so that alarms are triggered when the power strip is in an armed state and an electrical appliance is removed from a power outlet on the strip. Examples of such intelligent power strips that can be configured with a wireless transceiver to serve as a wireless node 102 are described in US Pat. App. Pub. 2017/0116832 and U.S. patent application Ser. No. 16/1117,304, filed Aug. 30, 2018, and entitled “Power And/Or Alarming Security System for Electrical Appliances”, the entire disclosures of which are incorporated herein by reference. Further still, the power strip could also be configured to detect identifiers for electrical appliances powered by the power strip (where these identifiers can serve as Product IDs). Such Product IDs could then be paired with the Strip IDs to track which products are connected with which power strips (or even with which power outlets within which power strips). For example, if the power strip provides DC power to a connected device such as a USB device (e.g., a smart phone or the like), then Product IDs can be determined by the power strip in response to its connection with the device. For a power strip that provides AC power to a connected device (e.g., where the connected device is a television set, vacuum cleaner, etc.), the power strip may be able to categorize the connected device as being a particular type of device based on a profile of its electrical characteristics as measurable by the power strip, and such type information can be used as a Product ID. In another example for AC power strips, a manual process of determining a Product ID for devices connected to the power strip could be used (e.g., a reader such as a bar code reader being used by store personnel to scan a device connected to the strip and obtain a Product ID that can be paired with a power strip identifier (or even a socket identifier of the power strip). Also, a process flow similar to that of FIG. 6 can be performed by the power strip to log events such as arm/disarm commands from authorized users and then wirelessly share the event log data with a remote computer system such as gateway computer 110 and/or server 120.

As yet another example, the wireless nodes 102 can correspond to different shelves or peg hooks within a retail store. Location awareness operations similar to those described by FIGS. 4A-4D can be performed to track where a given shelf or peg hook is being used within a retail store, where identifiers for the shelves and/or peg hooks are associated with locations for those shelves and/or peg hooks via a data structure. Further still, the shelf or hook could also be configured with an RFID reader or other sensor that would be capable of detecting RFID-equipped (or other sensible) products being moved onto the subject shelf or hook to detect identifiers for such products. Such Product IDs could then be paired with Shelf IDs/Hook IDs for the wireless nodes 102 to track which products are on which shelves or hooks. Also, a process flow similar to that of FIG. 6 can be performed by the shelf or hook to log events such as products being added or removed from the shelves hooks (or events such as arming or disarming if the shelf or hook is capable of being armed/disarmed) and then wirelessly share the event log data with a remote computer system such as gateway computer 110 and/or server 120.

Hybrid Wireless Environment with Different Types of Wireless Nodes:

Further still, in perhaps an even more powerful example embodiment, the system 100 can include multiple different types of wireless nodes 102 within wireless network 104 so that the gateway computer 110 and server 120 can monitor and control a hybrid mix of wireless nodes 102. As an example, the hybrid mix of wireless nodes 102 can include two or more of the following different types of nodes: a product display assembly, a display shelf, a display hook (e.g., a peg hook), a lock, a power outlet, a power strip, an audio/video controller, a camera, a sensor, a status indicator, a docking station, goods, etc.

An example of such a hybrid wirelessly connected environment is shown by FIG. 7A. In this example, the wireless nodes 102 include (1) a plurality of wireless nodes 102 corresponding to product display assemblies (PDAs), (2) a plurality of wireless nodes 102 corresponding to locks, and (3) a plurality of wireless nodes 102 corresponding to power strips. However, it should be understood that the hybrid system may include only two different types of wireless nodes 102. Furthermore, the hybrid system may include different mixes of different types of wireless nodes 102 than those shown by the example of FIG. 7A (e.g., where the system 100 includes wireless nodes 102 corresponding to PDAs and hooks, etc.). A practitioner may choose to include any combination of different types of wireless nodes 102 within system 100.

FIG. 7B shows an example data structure 700 that can be employed by the gateway computer 110 and/or server 120 to track data for the different types of wireless nodes 102. A data structure 702 (which may take the form of a table or the like) can associate different identifiers for the wireless nodes 102 (Node IDs) with the appropriate type of node for the wireless node 102 corresponding to the subject Node ID. Thus, Node IDs that correspond to product display assemblies 202 can be associated with a node type that corresponds to product display assemblies 202. Similarly. Node IDs that correspond to locks can be associated with a node type that corresponds to locks, and Node IDs that correspond to hooks can be associated with a node type that corresponds to power strips. Each Node ID for a particular node type can further be associated with data such as data structures 704, 706, and 708.

Data structure 704 comprises additional data that can be associated with wireless nodes 102 corresponding to PDAs. Data structure 704 can include fields similar to those discussed above for data structure 422, and can also include additional status information about each subject Node ID (where in this example, the Node ID can correspond to a Puck ID, although it should be understood that this need not be the case). The data included in such status information can be wirelessly communicated from the wireless nodes 102 to the gateway computer 110 and/or server 120 via the wireless network 104. An example of status information that can be included in data structure 704 comprises an indicator as to whether the subject PDA is currently armed or disarmed. Another example of status information that can be included in data structure 704 comprises access event log data such as described above in connection with FIG. 6 (e.g., logs of who did what and when with respect to the PDA, such as which user badge was used to control the PDA, what code or password was used to arm/disarm, etc.). Another example of status information that can be included in data structure 704 comprises lift data or the like that tracks customer interaction with the PDA (see, for example, FIG. 13G which shows an example GUI that presents data about tracked lifts with respect PDAs in a store). Yet another example of status information that can be included in data structure 704 comprises data that reflects a diagnostic and/or health status for the device corresponding to the subject Device ID (e.g., current status and/or charge level for a battery in the device, a temperature status for the device, etc.). Still more examples of status information that can be included in data structure 704 comprise health and/or diagnostic data about the PDA (e.g., whether is the PDA is charging devices properly, a charge level for a battery included in the puck assembly 302, over-current events, etc.). The status information can also include timestamps for all such data items. Thus, as an example, it should be understood that as different electronic devices 206 are moved to different PDAs, the Device IDs tied to given post positions may change, and the time stamps can allow the system to track such changes which supports forensic auditing of each PDA within the system 100.

Data structure 706 comprises additional data that can be associated with wireless nodes 102 corresponding to locks. Data structure 706 can include fields similar to those discussed above for data structure 422 (where the lock location field serves to identify a location for a given lock in a store, and where the Node ID field serves to identify a particular lock), and can also include additional status information about each subject Node ID (where in this example, the Node ID can correspond to a Lock ID). The data included in such status information can be wirelessly communicated from the wireless nodes 102 to the gateway computer 110 and/or server 120 via the wireless network 104. An example of status information that can be included in data structure 706 comprises an indicator as to whether the subject lock is currently locked or unlocked. Another example of status information that can be included in data structure 706 comprises access event log data such as described above in connection with FIG. 6 (e.g., logs of who did what and when with respect to the lock, such as which user badge was used to control the lock, what code or password was used to lock/unlock, etc.). Another example of status information that can be included in data structure 706 comprises data indicative of the products or type of products that are secured by the subject lock. Still more examples of status information that can be included in data structure 706 comprise health and/or diagnostic data about the lock (e.g., whether is the lock is operating properly, etc.). The status information can also include timestamps for all such data items which supports forensic auditing of each lock within the system 100 (see, for example, FIG. 13F which shows an example GUI that tracks users and their interactions with various locks in a store, where each user can be identified by a name and user identifier code, and where each user's dates/times/durations of interactions with identified locks can be presented).

Data structure 708 comprises additional data that can be associated with wireless nodes 102 corresponding to power strips. Data structure 708 can include fields similar to those discussed above for data structure 422 (where the power strip location field serves to identify a location for a given power strip in a store, where the Node ID field serves to identify a particular power strip, and where the Product Type ID field serves to identify a product type connected to the power strip), and can also include additional status information about each subject Node ID (where in this example, the Node ID can correspond to a Power Strip ID). The data included in such status information can be wirelessly communicated from the wireless nodes 102 to the gateway computer 110 and/or server 120 via the wireless network 104. An example of status information that can be included in data structure 708 comprises an indicator as to whether the subject power strip is currently armed or disarmed (if applicable). Another example of status information that can be included in data structure 708 comprises access event log data such as described above in connection with FIG. 6 (e.g., logs of who did what and when with respect to the power strip, such as which user badge was used to control the power strip, what code or password was used to arm/disarm, etc.) and/or power strip interaction data (such as product removals or additions to the power strip). Another example of status information that can be included in data structure 708 comprises data indicative of the product identifiers such as SKUs that are displayed via the power strip. Still more examples of status information that can be included in data structure 708 comprise health and/or diagnostic data about the power strip (e.g., whether is the power strip is operating properly, etc.). The status information can also include timestamps for all such data items which supports forensic auditing of each power strip within the system 100.

Through data structure 700, the gateway computer 110 and/or server 120 can serve as a common repository and access point for users to monitor and control different types of wireless nodes 102 within an environment such as one or more retail stores. This is a dramatic improvement over conventional systems where any such management if possible at all was occurring through distinct systems such that users were forced to configured, access, and use disparate computer systems that lacked a singular, holistic view of a larger hybrid environment.

For example, different types of wireless nodes 102 can have different management/control process flows, and because system 100 provides a common repository for data about different types of wireless nodes 102, the system 100 can also support selective execution of appropriate management/control flows for different node types from a common computer system. An example of this is shown by FIG. 8A. FIG. 8A shows a memory 810 that may be part of the gateway computer 110 and/or server 120, where this memory includes different program instructions for different types of wireless nodes 102. For example, the memory 810 may include (1) management/control flow program instructions 820 for a first node type, (2) management/control flow program instructions 822 for a second node type, and (3) management/control flow program instructions 824 for a third node type. A processor of gateway computer 110 and/or server 120 can interact with data structure 702 and memory 810 (where data structure 702 may be stored in memory 810) to perform the process flow of FIG. 8A. At step 800, the processor determines the node type of interest (e.g., a PDA, lock, etc.) At step 802, the processor selects the appropriate management/control flow program instructions for the determined node type from memory 810. At step 804, the processor executes the selected management/control flow program instructions to thereby provide the management and control that is specific to a particular node type, all from a common computer system for the different node types. The instructions for the various management/control process flows can be embodied as a plurality of processor-executable instructions that are resident on a non-transitory computer-readable storage medium (such as memory 810).

FIG. 8B further shows how such management and control over different node types can be provided from a common user interface. At step 850, a user who is requesting access to system 100 is authenticated to confirm that he or she is an authorized user. As discussed in the above-referenced and incorporated US Pat App Pub 2017/0164314, the system can employ permission levels to restrict a user's access to only data to which he or she is entitled to review or control (e.g., a manager at Store A can have an assigned permission level that allows him or her to access data about wireless nodes in Store A but not data about wireless nodes in Store B; while a regional manager for a chain of stores may get access to data from wireless nodes in the stores encompassed by the manager's region, and so on). After authentication, the system can present the user with a graphical user interface (GUI) that provides a view of multiple type of wireless nodes 102. As an example, such a GUI can be provided through interface 130 and be presented on a tablet computer or the like. FIG. 13A shows an example where a user who is a corporate level user can view a list of stores that include wireless nodes 102 being tracked by the system. In response to user selection of a particular store, a store-specific GUI can be presented. FIG. 13B shows an example of a GUI for a store where different types of wireless nodes 102 are present (see lock nodes 1300 and PDA nodes 1302). If a user is only authorized to view wireless node data for a particular store, then a landing page after authentication for such a user could be a GUI such as that shown by FIG. 13B. In the example of FIG. 13B, this GUI can list or display the different types of wireless nodes 102 that are supported by the system, and the GUI can be responsive to user input (which may include touch input through a touchscreen if the GUI is touchscreen-enabled) to select one or more of the listed node types. At step 854, the system receives a node type selection from the user. At this point, the system can then select and execute the appropriate management/control flow for the selected node type (see, e.g., FIG. 8A). As such, users can be provided with a common interface for managing and controlling different types of wireless nodes 102 within system 100.

FIG. 9 shows an example management/control flow with respect to product display assemblies (PDAs) 202 as wireless nodes 102. At step 900, a user is authenticated to confirm that the user is an authorized user. If the FIG. 9 process flow is performed in conjunction with the FIG. 8B process flow (e.g., as part of steps 856, 858, or 860), then it should be understood that step 900 may be omitted as step 850 would have already authenticated the authorized user. However, it should be understood that the FIG. 9 process flow need not only be performed in a hybrid system 100 with different types of wireless nodes 102; the FIG. 9 process flow could also be performed as part of a system 100 where all of the wireless nodes 102 correspond to PDAs 202.

At step 902, a GUI is presented to the user that provides the user with a view of the subject PDAs. As an example, if the user is a manager of a particular retail store, this GUI can provide a visual mapping of different PDAs within the retail store. Each PDA can be shown via a graphical icon or the like and be positioned in a spatial arrangement on the GUI having a relationship to the tracked location of that PDA within the store. FIG. 13C shows an example GUI for this. As shown by FIG. 13C, a room with multiple tables and other display location is graphically illustrated in an upper portion of the GUI. The locations of various PDAs within the room can be graphically depicted via colored circles within the room illustration. A list in the lower portion of the GUI can then list different sections of the room. In response to user selection, the GUI can focus in on the selected section (e.g., focusing in on the section labeled “MTI Showroom East”). The GUI also shows a security status for the PDAs in the various sections (and where user input via a swiping action can cause the system to issue an arm/disarm command to the PDAs in a particular section). FIG. 13D shows a GUI that has been focused on a particular section listed in FIG. 13C (which is “MTI Showroom East” in this example). In the GUI of FIG. 13D, a table with multiple PDAs in a particular showroom is presented in the upper portion of the GUI, and each PDA is graphically shown as a circle on a table surface. The lower portion of the GUI lists different tables that are present in the subject showroom. Selection of a listed table can cause the GUI to show table-specific PDAs. The GUI also shows a security status for the PDAs on the various tables (and where user input via a swiping action can cause the system to issue an arm/disarm command to PDAs for the selected section and/or table). The PDAs can also or alternatively be presented as a list of PDAs (e.g., a textual list of PDA 1, PDA 2, etc.), where such a list need not provide any location awareness information. The different PDAs may be identified by their known post positions to make them easily identifiable to users. However, it should be understood that the GUI could sort and list the PDAs using any of a number of different manners of presentation. For example, the list can present PDAs alphabetically. In other example, the list can order the PDAs on the basis of a criticality criteria (e.g., any PDAs showing an alarm status or some other operational anomaly could be bumped higher on the list than PDAs that show normal status). For this type of presentation, tiers of criticality could be used (e.g., tier 1 or “red” warnings for PDAs with an active alarm status, tier 2 or “yellow” warnings for PDAs that show some other anomaly (e.g., see FIG. 13E (which shows a PDA that is flagged for not properly charging a device); or as another example, a PDA being in a disarmed state for longer than a defined threshold), and tier 3 for PDAs that are operating normally. The GUIs may be designed in a fashion that allows the user to selectably control how PDAs are listed or displayed.

The GUI can be configured to accept a variety of different user inputs. For example, each displayed or listed PDA can be selectable by a user (e.g., via a touch input, link selection, etc.). User inputs can also be provided for actions such as arming/disarming one or more PDAs, and requesting some form of action with respect to one or more PDAs (e.g., changing which device 206 is presented by a particular PDA, requesting maintenance for a particular PDA, etc.). At step 904, user input can be received via the GUI.

If the user input at step 904 corresponds to a selection of a particular PDA, then the process flow can proceed to step 910. At step 910, the system can retrieve data about the selected PDA (e.g., data from data structure 704 for the selected PDA), and this retrieved data can be presented to the user via a GUI. As an example, such a GUI can identify where the subject PDA is located, whether the subject PDA is currently armed/disarmed, what device 206 is connected to the PDA, a current charge level for a battery in device 206, how many customer interactions with the PDA has occurred over some defined time duration, etc.). FIG. 13E shows an example GUI that lists different PDAs, and where a particular PDA that exhibits a charging issue has been selected for presentation to the user. This GUI shows how a detected health condition such as a device not charging properly can be flagged to users. The GUI also shows how the GUI can propose a solution to the identified problem. The “Identify” button in FIG. 13E can be selected by the user to cause the system to wirelessly transmit a command to the subject PDA that will cause a status indicator on the subject PDA to call attention to the subject PDA. This can help a user identify the PDA that needs to be serviced. Such a GUI may also provide an event log history for the subject PDA (or include a selectable button or link for accessing and presenting such a log history). Such a GUI can also be capable of receiving user input that corresponds to a request from the user to arm or disarm the subject PDA. Further still, such a GUI can also be capable of receiving user input that corresponds to an action request with respect to the subject PDA.

If the user input at step 904 corresponds to a request to arm or disarm a PDA, then the process flow can proceed to step 920. At step 920, the system wirelessly sends an arm/disarm command to the subject PDA 202 via gateway computer 110 and the wireless network 104. In example embodiments where the wireless network 104 is arranged as a wireless mesh network, the mesh network can help reliably deliver this command to the subject PDA even if a direct link between the gateway computer 110 and the subject PDA is not available at that time. Given that retail stores are accepted to be noisy signal environments, the mesh network configuration can be particularly advantageous. The PDA 202 can be configured to wirelessly send an acknowledgement message back to the gateway computer 110 in response to receipt of the arm/disarm command to confirm that the command was received and followed. At step 922, the system can check for this acknowledgement message from the subject PDA. If received, the process flow can proceed to step 924 and update the GUI to show a change in the armed/disarmed status for the subject PDA. If no acknowledgement message is received, an error notification can be generated, which may result in an employee being flagged to check on the subject PDA to assess whether the subject PDA is armed or disarmed.

If the user input at step 904 corresponds to an action request for a PDA, then the process flow can proceed to step 930. At step 930, user input can be received through a GUI that defines the nature of the specific action request. For example, the GUI can provide a text entry field through which a user can request that an action be taken such as changing the device 206 that is displayed via a PDA or installing a new puck assembly 302 at the PDA. Similarly, a GUI could provide a menu of selectable predefined action requests (e.g., “Check PDA”, “Install New Puck at PDA”, etc.). At step 932, the system generates a notification message based on the action request user input from step 930. Then, at step 934, the system sends this notification message to a responsible party so that the action request can be implemented. This message can then be received on a tablet computer, smart phone, or other device carried by the responsible party so that the responsible party can be informed of the need to take the requested action. Thus, the system can also store a data structure that maintains a contact list for different responsible parties (e.g., employees within a retail store), where the system will include an assignment mechanism for assigning action request messages to people on the contact list according to availability data maintained by the system (e.g., who is on shift, etc.).

FIG. 10 shows an example management/control flow with respect to locks as wireless nodes 102. At step 1000, a user is authenticated to confirm that the user is an authorized user. If the FIG. 10 process flow is performed in conjunction with the FIG. 8B process flow (e.g., as part of steps 856, 858, or 860), then it should be understood that step 1000 may be omitted as step 850 would have already authenticated the authorized user. However, it should be understood that the FIG. 10 process flow need not only be performed in a hybrid system 100 with different types of wireless nodes 102; the FIG. 10 process flow could also be performed as part of a system 100 where all of the wireless nodes 102 correspond to locks.

At step 1002, a GUI is presented to the user that provides the user with a view of the subject locks. As an example, if the user is a manager of a particular retail store, this GUI can provide a visual mapping of different locks within the retail store. Each lock can be shown via a graphical icon or the like and be positioned in a spatial arrangement on the GUI having a relationship to the tracked location of that lock within the store. The locks can also or alternatively be presented as a list of locks (e.g., a textual list of Lock 1, Lock 2, etc.). The different locks may be identified by their known lock positions to make them easily identifiable to users (e.g., Cabinet A1, Cabinet A2, etc.). The GUI can be configured to accept a variety of different user inputs. For example, each displayed or listed lock can be selectable by a user (e.g., via a touch input, link selection, etc.). User inputs can also be provided for actions such as locking/unlocking one or more locks, and requesting some form of action with respect to one or more locks (e.g., changing the items within an enclosure protected by a lock, requesting maintenance for a particular lock, etc.). At step 1004, user input can be received via the GUI.

If the user input at step 1004 corresponds to a selection of a particular lock, then the process flow can proceed to step 1010. At step 1010, the system can retrieve data about the selected lock (e.g., data from data structure 706 for the selected lock), and this retrieved data can be presented to the user via a GUI. As an example, such a GUI can identify where the subject lock is located, whether the subject lock is currently locked or unlocked, what items are within an enclosure protected by the lock, etc.). Such a GUI may also provide an access log history for the subject lock (or include a selectable button or link for accessing and presenting such a log history). Such a GUI can also be capable of receiving user input that corresponds to a request from the user to lock or unlock the subject lock. Further still, such a GUI can also be capable of receiving user input that corresponds to an action request with respect to the subject lock.

If the user input at step 1004 corresponds to a request to lock or unlock a lock, then the process flow can proceed to step 1020. At step 1020, the system wirelessly sends a lock/unlock command to the subject lock via gateway computer 110 and the wireless network 104. In example embodiments where the wireless network 104 is arranged as a wireless mesh network, the mesh network can help reliably deliver this command to the subject lock even if a direct link between the gateway computer 110 and the subject lock is not available at that time. Given that retail stores are accepted to be noisy signal environments, the mesh network configuration can be particularly advantageous. The lock can be configured to wirelessly send an acknowledgement message back to the gateway computer 110 in response to receipt of the lock/unlock command to confirm that the command was received and followed. At step 1022, the system can check for this acknowledgement message from the subject lock. If received, the process flow can proceed to step 1024 and update the GUI to show a change in the locked/unlocked status for the subject lock. If no acknowledgement message is received, an error notification can be generated, which may result in an employee being flagged to check on the subject lock to assess whether the subject PDA is locked or unlocked.

If the user input at step 1004 corresponds to an action request for a lock, then the process flow can proceed to step 1030. At step 1030, user input can be received through a GUI that defines the nature of the specific action request. For example, the GUI can provide a text entry field through which a user can request that an action be taken such as changing the item(s) within the enclosure protected by the subject lock. Similarly, a GUI could provide a menu of selectable predefined action requests (e.g., “Check Lock”, “Install Lock”, etc.). At step 1032, the system generates a notification message based on the action request user input from step 1030. Then, at step 1034, the system sends this notification message to a responsible party so that the action request can be implemented. This message can then be received on a tablet computer, smart phone, or other device carried by the responsible party so that the responsible party can be informed of the need to take the requested action. Thus, the system can also store a data structure that maintains a contact list for different responsible parties (e.g., employees within a retail store), where the system will include an assignment mechanism for assigning action request messages to people on the contact list according to availability data maintained by the system (e.g., who is on shift, etc.).

FIG. 11 shows an example management/control flow with respect to power strips as wireless nodes 102. At step 1100, a user is authenticated to confirm that the user is an authorized user. If the FIG. 11 process flow is performed in conjunction with the FIG. 8B process flow (e.g., as part of steps 856, 858, or 860), then it should be understood that step 1100 may be omitted as step 850 would have already authenticated the authorized user. However, it should be understood that the FIG. 11 process flow need not only be performed in a hybrid system 100 with different types of wireless nodes 102; the FIG. 11 process flow could also be performed as part of a system 100 where all of the wireless nodes 102 correspond to power strips.

At step 1102, a GUI is presented to the user that provides the user with a view of the subject power strips. As an example, if the user is a manager of a particular retail store, this GUI can provide a visual mapping of different power strips within the retail store. Each power strip can be shown via a graphical icon or the like and be positioned in a spatial arrangement on the GUI having a relationship to the tracked location of that power strip within the store. The power strips can also or alternatively be presented as a list of power strips (e.g., a textual list of Power Strip 1, Power Strip 2, etc.). The different power strips may be identified by their known store positions to make them easily identifiable to users (e.g., Table 1, Table 2, etc.). The GUI can be configured to accept a variety of different user inputs. For example, each displayed or listed power strip can be selectable by a user (e.g., via a touch input, link selection, etc.). User inputs can also be provided for actions such as arming/disarming one or more power strips (and/or individual power outlets on power strips), and requesting some form of action with respect to one or more power strips (e.g., changing which electrical appliance is connected to a power strip, requesting maintenance for a particular power strip, etc.). At step 1104, user input can be received via the GUI.

If the user input at step 1104 corresponds to a selection of a particular power strip, then the process flow can proceed to step 1110. At step 1110, the system can retrieve data about the selected power strip (e.g., data from data structure 708 for the selected power strip), and this retrieved data can be presented to the user via a GUI. As an example, such a GUI can identify where the subject power strip is located, whether the subject power strip is currently armed/disarmed, what electrical appliances are connected to the power strip (if such information is available for the strip), etc.). Such a GUI could be similar in nature to those shown for PDAs with respect to FIGS. 13C and 13D. Such a GUI may also provide an event log history for the subject power strip (or include a selectable button or link for accessing and presenting such a log history). Such a GUI can also be capable of receiving user input that corresponds to a request from the user to arm or disarm the subject power strip. Further still, such a GUI can also be capable of receiving user input that corresponds to an action request with respect to the subject power strip.

If the user input at step 1104 corresponds to a request to arm or disarm a power strip, then the process flow can proceed to step 1120. In an example embodiment, this command can be applicable to a power strip as a whole. However, in another example embodiment, this command can be specific to an individual power outlet within a power strip. At step 1120, the system wirelessly sends an arm/disarm command to the subject power strip via gateway computer 110 and the wireless network 104. In example embodiments where the wireless network 104 is arranged as a wireless mesh network, the mesh network can help reliably deliver this command to the subject power strip even if a direct link between the gateway computer 110 and the subject power strip is not available at that time. Given that retail stores are accepted to be noisy signal environments, the mesh network configuration can be particularly advantageous. The power strip can be configured to wirelessly send an acknowledgement message back to the gateway computer 110 in response to receipt of the arm/disarm command to confirm that the command was received and followed. At step 1122, the system can check for this acknowledgement message from the subject power strip. If received, the process flow can proceed to step 1124 and update the GUI to show a change in the armed/disarmed status for the subject power strip. If no acknowledgement message is received, an error notification can be generated, which may result in an employee being flagged to check on the subject power strip to assess whether the subject power strip (or specific power outlet in the subject power strip) is armed or disarmed.

If the user input at step 1104 corresponds to an action request for a power strip, then the process flow can proceed to step 1130. At step 1130, user input can be received through a GUI that defines the nature of the specific action request. For example, the GUI can provide a text entry field through which a user can request that an action be taken such as changing an electrical appliance that is connected to the power strip. Similarly, a GUI could provide a menu of selectable predefined action requests (e.g., “Check Power Strip”. “Remove Power Strip”, etc.). At step 1132, the system generates a notification message based on the action request user input from step 1130. Then, at step 1134, the system sends this notification message to a responsible party so that the action request can be implemented. This message can then be received on a tablet computer, smart phone, or other device carried by the responsible party so that the responsible party can be informed of the need to take the requested action. Thus, the system can also store a data structure that maintains a contact list for different responsible parties (e.g., employees within a retail store), where the system will include an assignment mechanism for assigning action request messages to people on the contact list according to availability data maintained by the system (e.g., who is on shift, etc.).

While FIGS. 9-11 show examples of management/control flows for different types of wireless nodes 102, it should be understood that such management/control flows could be designed to perform different tasks if desired by a practitioner. Furthermore, while FIGS. 9-11 show examples of management/control flows for PDAs, locks, and power strips respectively, it should be understood that similar management/control flows can be implemented for other types of wireless nodes 102 (e.g., peg hooks, shelves, etc.).

FIG. 12 shows an example process flow for alert generation with respect to a wireless node 102 in the system 100. Such a process flow can be executed by gateway computer 110 and/or server 120 automatically as new data is received from wireless nodes 102, or it can be executed on demand in response to user requests. At step 1200, the system compares the status information for a wireless node 102 with one or more conditions. An example of such conditions could be planogram data for PDAs 202 in a store. The planogram data can identify which post positions are slated to display which device types. Step 1200 can compare the data in data structure 422/704 with such planogram data to assess planogram compliance. Another example of such conditions could be a battery charge threshold for a battery of an electronic device 206 displayed via a PDA 202. Step 1200 can compare battery status data that may be present in table 704 with the threshold to assess whether any electronic devices 206 are under-charged. Such an under-charge scenario could indicate that a maintenance need exists. Yet another example of such conditions could be a temperature threshold for a battery of an electronic device 206 displayed via a PDA 202. Step 1200 can compare temperature data that may be present in table 704 with the threshold to assess whether any electronic devices 206 are running hot. If so, it may be desirable to disconnect the electronic device 206 from power. As yet another example, the condition could be a time threshold that is used to assess whether a PDA has been left unarmed for too long or whether a lock has been left unlocked for too long. These are just some examples of various conditions that could be tested at step 1200.

At step 1202, the system generates an alert message about the wireless node(s) 102 in question if the comparison at step 1200 indicates that an alert is needed. This alert message can identify the subject wireless node(s) and location as well as the nature of the issue that triggered the alert (e.g., POG non-compliance, unlocked for too long, etc.). At step 1204, the system sends the alert message as a notification to a responsible party. The alert notification message can then be received on a tablet computer, smart phone, or other device carried by the responsible party so that the responsible party can be informed about the alert. As noted above, the system can also store a data structure that maintains a contact list for different responsible parties (e.g., employees within a retail store), and the system can include an assignment mechanism for assigning alert notification messages to people on the contact list according to availability data maintained by the system (e.g., who is on shift, etc.).

Proxy Nodes for Expanded Functionality of Wireless Nodes:

Furthermore, in additional example embodiments, the use of proxy nodes are disclosed for expanding the functionality of one or more wireless nodes 102 in the wireless network 104. For example, it may be the case that some of the wireless nodes 102 correspond to devices with limited functionality. For example, a product display assembly 202 in the wireless network 104 may be configured with circuitry for reading a first type of user credentials from a user in order to support a decision as to whether the user is authorized to perform an action such as arming and/or disarming the product display assembly 202. However, the existing circuitry of the product display assembly 202 may not support reading a second type of user credentials. Rather than forcing a hardware retrofit of the product display assembly 202 to enable the product display assembly 202 to read the second type of user credentials, which may be challenging and costly, a proxy node can be added to the wireless network 104 to upgrade the product display assembly 202 via a proxy function.

FIG. 14A shows an example embodiment for the use of a proxy node 1400 to augment the feature set of one or more wireless nodes 102. The proxy node 1400 can include a wireless transceiver 1402 that allows the proxy node to wirelessly communicate on the wireless network 104. The proxy node 1400 can also include a circuit 1404 that provides a circuit function. Through the wireless communications by the wireless transceiver 1402 on wireless network 104, the circuit function can be made available to one or more of the wireless nodes 102 via proxy. The circuit 1404 can take the form of any of a number of circuits that provide a desired function. An example of circuit 1404 may include a reader circuit that reads a user authorization credential presented by a user. For example, the reader circuit could take the form of an RFID reader that is capable of reading a code from an RFID card presented by a user. This code can then be authenticated locally by the circuit 1404 and/or communicated over wireless network 104 to the gateway computer 110 for remote authentication. Examples of techniques for user authentication are described in the above-referenced and incorporated U.S. Pat. No. 9,892,604 and U.S. Pat. App. Pub. 2017/0300721. However, as explained below with reference to additional examples, the circuit 1404 can take forms other than a reader circuit.

The proxy node 1400 can include a circuit board on which the wireless transceiver 1402 and circuit 1404 are deployed. The proxy node 1400 and its circuit board may also include additional components, such as a power source (not shown) (e.g., a battery), a user interface (not shown) (e.g. keypad, display screen, touch screen, etc.) and other components if desired by a practitioner.

FIG. 14B depicts an example process flow showing how the proxy node 1400 can be used to augment the feature set of one or more wireless nodes 102. At step 1410, the proxy node 1400 is associated with one or more wireless nodes 102. This association can then be stored in a data structure within the system 100. At step 1412, the proxy node 1400 wirelessly communicates over the wireless network 104 with gateway computer 110 and/or its associated wireless node(s) as necessary to make the function of circuit 1404 available to the associated wireless node(s) via proxy.

FIG. 15 shows an example proxy node architecture where the circuit 1404 can provide any combination of proxy features to its associated wireless node(s). Through a wireless communication bridge between the proxy node 1400, gateway computer 110, and associated wireless node(s) 102, the proxy node 1400 can communicate with any other device reachable via the network 104, including server 120 (via gateway computer 110).

As noted above, the circuit 1404 can include a reader circuit such as an RFID reader (see Proxy Feature #1 in FIG. 15). In this fashion, an associated wireless node 102 that lacks an ability to perform the same type of read operation can be augmented via proxy with such a capability.

As another example, the circuit 1404 can include a visual indicator circuit (see Proxy Features #2 and #4 in FIG. 15). The proxy node 1400 can then interact wirelessly with its associated wireless node(s) 102 and/or the gateway computer 110 to obtain operational status data about the associated wireless node(s) 102. As examples, the operational status could be information such as whether the associated wireless node 102 is armed or disarmed, whether it is operating properly, whether it is in an alarm state, etc. The proxy node 1400 can then actuate its visual indicator circuit to provide a visual indication of such operational status. The visual indicator circuit can include one or more light emitting diodes (LEDs) to provide the visual indication, or it can include more complex components such as a display screen or a touch screen that provides such a visual indication of operational status.

As another example, the circuit 1404 can include a sounder circuit that produces an audible sound in response to actuation. For example, it may be the case that a practitioner wants to augment the associated wireless node 102 with a higher power alarm sound than is available from a pre-existing sounder circuit in the associated wireless node 102. The proxy node 1400 can then interact wirelessly with its associated wireless node(s) 102 and/or the gateway computer 110 to obtain a sound trigger command (e.g., an alarm signal) about the associated wireless node(s) 102. The proxy node 1400 can then actuate its sounder circuit to produce the appropriate higher power audible sound.

As another example, the circuit 1404 can include an interface circuit for connecting the proxy node 1400 with another device 1500 that is not itself connected to the wireless network 104 (see Proxy Feature #5 in FIG. 15). In this manner, the interface circuit provides a bridging function between the wireless network 104 and device 1500. The connection between the proxy node 1400 and the device 1500 through the interface circuit can be via a wired or wireless interface 1502. In a retail store environment, device 1500 may be a third-party device such as a product display assembly that does not itself have access to the wireless network 104. If the device 1500 includes a defined interface that is known to the proxy node 1400, the proxy node 1400 can then communicate with the device 1500 via its interface circuit. In this fashion, the proxy node 1400 can relay messages from its associated wireless node(s) 102 and/or the gateway computer 110 to the device 1500 (and vice versa for messages from device 1500 to associated wireless node(s) 102 and/or gateway computer 110).

In yet more examples, the circuit 1404 could take other forms. For example, if an associated wireless node 102 does not have a particular sensor, the proxy node 1400 can provide such a sensor to the associated wireless node 102 via proxy. Examples of sensors that could be supported by circuit 1404 include proximity sensors, microphones, light sensors, motion detectors, acceleration sensors, temperature sensors, touch sensors, pressure sensors, and/or voltage/current/power sensors. In terms of output generation, the circuit 1404 can also provide a haptic output capability rather than audio or visual outputs, if desired.

FIGS. 16A-16C show examples of communication arrangements that can be supported by the proxy node 1400 in connection with step 1412 of FIG. 14B.

In the example of FIG. 16A, communications between the proxy node 1400 and its associated wireless nodes 102 (see 1600 in FIG. 16A) take place indirectly via the gateway computer 110. Thus, if the proxy node 1400 is to send a message or command to one of its associated wireless nodes 102, it can do so via a wireless communication 1602 over wireless network 104 with the gateway computer 110. The gateway computer 110 can then relay this message to the subject associated wireless node 102 via a wireless communication 1604 over the wireless network 104. The gateway computer 110 can include a memory that stores a data structure 1610 that associates the proxy node 1400 with its associated wireless node(s) 102. Such a data structure can take the form of an association table, as discussed below. The association table 1610 can include identifying information for the associated wireless node(s) 102 (e.g., a Wireless Node ID) and/or addressing information for the associated wireless node(s) 102 (e.g., a network address for the subject wireless node 102 on the wireless network 104). The association table 1610 may also include similar information for the proxy node 1400. The proxy node 1400 can include its own identifier or network address in its message to the gateway computer 110, and the gateway computer 110 can then look up the associated wireless node 102 in the association table 1610 so that it can relay the message appropriately. If the proxy node 1400 is associated with multiple wireless nodes 102, its message to the gateway computer 110 may include an identification of a specific wireless node destination if the message is not to be relayed to all of its associated wireless nodes. Similar techniques can be used by the gateway computer 110 to relay messages from associated wireless node(s) 102 to the proxy node 1400 if desired.

As an example of a proxy function that can be provided by the architecture of FIG. 16A, we can consider the reader circuit example where the proxy node 1400 operates to read a type of user credentials that the associated wireless node(s) cannot read. In such a situation, a user can interact with the proxy node 1400 so that the reader circuit reads the user's user authorization credentials (e.g., reading an RFID card presented by the user). The proxy node 1400 can then send a message to the gateway computer 110 via wireless communication 1602, where this message includes data that represents the read user authorization credentials as well as identifies the proxy node 1400. The gateway computer 110 can then make an authentication decision about the user based on such user authorization credentials. The result of this authentication decision is then sent to the associated wireless node(s) 102 via wireless communications 1604. To appropriately direct the authentication decision, the gateway computer 110 can access the association table 1610 to identify the associated wireless nodes 102 and their addressing information that are linked to the subject proxy node 1400. The messages sent via 1604 can then be addressed to the appropriate wireless nodes 102 based on the addressing information in the association table 1610 that is linked to the wireless nodes 102 associated with the subject proxy node 1400. The associated wireless nodes 102 can then receive such messages via 1604 and respond appropriately (e.g., arm itself, disarm itself, etc.).

In the example of FIG. 16B, communications between the proxy node 1400 and its associated wireless nodes 102 (see 1600 in FIG. 16B) take place directly via the wireless network 104 (rather than indirectly through the gateway computer 110 as a relay, as shown by FIG. 16A). If the wireless network 104 is a mesh network, it should be understood that this direct wireless communication may still be routed through one or more other wireless nodes 102 in the mesh if necessary. With the example embodiment of FIG. 16B, the gateway computer 110 may push its association table 1610 to the proxy node 1400 via a wireless communication 1620. The proxy node 1400 can include a processor and memory that cooperate together to store the association table 1610 in the proxy node's memory. The proxy node 1400 can then leverage the information in the association table 1610 to communicate with its associated wireless nodes 102 as necessary via wireless communications 1622 over the wireless network 104.

As an example of a proxy function that can be provided by the architecture of FIG. 16B, we can consider the sounder circuit example where the proxy node 1400 provides an audible alarm function for the associated wireless node(s) 102. In such a situation, the proxy node 1400 can periodically poll its associated wireless node(s) 102 for alarm status via messages sent to network addresses as determined from the local copy of the association table 1610 (see 1622 in FIG. 16B). If any of the associated wireless node(s) responds with a message to trigger the alarm (via 1622), the sounder circuit can be appropriately activated by the proxy node 1400.

In the example of FIG. 16C, the basic architecture of FIG. 16A is employed, but communications can be extended to remote server 120 via communications 1630 over a network such as the Internet or other wide area network. Server 120 can include a memory that stores the association table 1610, and table 1610 can be pushed down to lower elements in the system as necessary (e.g., to the gateway computer 110 and/or proxy node 1400). Furthermore, with an architecture such as that shown by FIG. 16C, it should be understood that server 120 can communicate with a number of different wireless networks 104, where each wireless network 104 can include a gateway computer 110, one or more wireless nodes 102, and one or more proxy nodes 104. For example, the different wireless networks 104 can be located in different retail stores, and the server 120 can provide views (which may be interactive views as discussed above) of the various nodes 102 (and proxy nodes 1400) located in the different retail stores.

FIGS. 17A-17C show example process flows for creating the association table 1610. In the example of FIG. 17A, the triggering action occurs on a proxy node 1400. In the example of FIG. 17B, the triggering action occurs on the gateway computer 110. In the example of FIG. 17C, the process occurs through a user interface such as may be available via a mobile or web application.

With reference to FIG. 17A, the process flow begins at step 1700 when a defined action is received by the proxy node 1400. This action can be any of a number of actions, such as the user presenting an appropriate user credential to the proxy node (e.g., an RFID card or other security fob such as an electronic key), the user pressing a button on the proxy node, etc. as may be supported by the proxy node 1400. In response to the defined action at step 1700, the system enters an enrollment mode (step 1702). During enrollment mode, one or more wireless nodes 102 can be associated with the subject proxy node 1400.

In enrollment mode, the system waits for a defined action to be received by a wireless node 102 to be associated with the proxy node 1400. This action can also be any of a number of actions, such as the user presenting an appropriate user credential to the subject wireless node 102 (e.g., an RFID card or other security fob such as an electronic key), the user pressing a button on the subject wireless node 102, etc. as may be supported by the wireless node 102. In response to the defined action at step 1704, the system creates an entry in the association table 1610 that associates the subject wireless node 102 with the subject proxy node 1400 (step 1706). Thereafter, the process flow checks whether an additional wireless node 102 is to be associated with the proxy node 1400. If so, the process flow of steps 1704 and 1706 is repeated. Otherwise, the enrollment mode terminates at step 1710 if a timeout or other defined action occurs that is operative to close the enrollment period.

In an example embodiment, step 1706 can be performed locally at the proxy node via wireless communications with the wireless nodes 102 over wireless network 104 or it can be performed by the gateway computer 110 via wireless communications with the wireless nodes 102 and proxy node 1400 over wireless network 104.

The process flow of FIG. 17B is similar to that of FIG. 17A, but begins with a defined action that is received by the gateway computer 110 (step 1720). This action can be any of a number of actions, such as the user presenting an appropriate user credential to the gateway computer 110 (e.g., an RFID card or other security fob such as an electronic key), the user pressing a button on the gateway computer, etc. as may be supported by the gateway computer 110. Furthermore, after entering the enrollment mode, step 1722 can look for defined actions on both the subject proxy node 1400 and the wireless node(s) 102 to be associated with the subject proxy node 1400 so that the system knows which components are to be associated with each other in association table 1610.

FIG. 17C depicts an example where associations are created via a user interface. At step 1730, a graphical user interface (GUI) is provided to a user, where the GUI provides a mechanism for associating proxy nodes with wireless nodes. Such a GUI can be available through a web application or mobile application that is made available via computers 110 and/or 120. At step 1732, the system gathers a list of available proxy nodes 1400 within a wireless network 104. This list may include one or more proxy nodes 1400 that are active within the wireless network 104. At step 1734, the system gathers a list of available wireless nodes 102 within the wireless network 104. This list may include one or more wireless nodes 102 that are active within the wireless network 104. Then, at step 1736, the GUI presents these lists to the user through a display that provides an input mechanism that permits the user to provide user input that selects one or more proxy nodes 1400 and one or more wireless nodes 102 that are to be associated with each other (step 1738). For example, the GUI can present each proxy node and each wireless node on the lists as a selectable icon, and the user can then select via a cursor selection or touchscreen input if available to identify the selected nodes. Another button can be user-selectable to create the association between the selected nodes. At step 1740, the system creates one or more associations in the association table 1610 between the selected proxy node(s) and the selected wireless node(s).

FIG. 17D shows an example association table 1610 that can identify one or more wireless nodes 102 that are associated with a proxy node 1400. The example of FIG. 17D is proxy node-specific in that it is assumed that all entries in the table are associated with a particular proxy node 1400. The table 1610 can include an identification 1750 of each the associated wireless node 102 (e.g., a Wireless Node ID if available within the system) and addressing information 1752 for the associated wireless node 102. The addressing information can take the form of a network address that can then be used by the proxy node 1400 to wirelessly communicate with its associated wireless nodes 102, either directly or indirectly. However, it should be understood that a practitioner may choose to include additional information in table 1610 if desired.

FIG. 17E shows another example association table 1610 that can identify one or more wireless nodes 102 that are associated with one or more proxy nodes 1400. The example of FIG. 17E can encompass multiple proxy nodes 1400 as it includes a column 1760 for identifying the subject proxy node 1400 and its associated wireless nodes 102. The proxy node identifier in column 1760 can be any suitable identifier for a proxy node 1400 within the system, and it should be understood that table 1610 may also include addressing information for such proxy nodes (e.g., each proxy node's network address on the wireless network). The table 1610 can also include fields 1750 and 1752 for the associated wireless nodes 102 as discussed above. Accordingly, it should be understood that table 1610 of FIG. 17E can be useful for a gateway computer 110 and/or server 120 where it may be necessary to track the associations between multiple proxy nodes 1400 and multiple wireless nodes 102. Once again, it should be understood that a practitioner may choose to include additional information in table 1610 of FIG. 17E if desired.

In yet another example embodiment, the proxy node 1400 may be integrated within a device 1500 in order to make device 1500 connectable to wireless network 104. An example is shown by FIG. 18. In such a fashion, a device 1500 that was not previously interoperable with wireless network 104 can then be linked into the wireless network 104 via the integrated proxy node 1400. The device 1500 can include circuitry that supports any of features 1800, where features 1800 can be like features to those described for circuit 1404 in connection with FIGS. 14A and 15. For example, device 1500 may be a third-party device relative to the device(s) corresponding to wireless node(s) 102, but it may have very similar functionality. However, because device 1500 is not natively interoperable with wireless network 104, the system is not able to remotely manage and control device 1500 like it can for wireless nodes 102. To augment the device 1500 and make it interoperable with wireless network 104, the device 1500 can include an API interface 1802. API interface 1802 can define a framework for communicating with the circuitry 1800. Circuit 1404 of proxy node 1400 can connect with API interface 1802 and provide any necessary signaling translation between the format supported by API interface 102 and the data formats supported on wireless network 104. In this fashion, the integrated proxy node 1400 can provide a bridge between device 1500 and the wireless network 104. Through such a bridge, the gateway computer 110 can access and collect operational status data (which may include usage statistics for customer interactions with device 1500—examples of such usage statistics are discussed above and in the above-referenced and incorporated patents and patent applications). To integrate proxy node 1400 with the device 1500, a circuit board that contains wireless transceiver 1402 and circuit 1404 can be placed inside device 1500 can connected to API interface 1802 (e.g., via a serial port or the like that is included as part of circuit 1404). Device 1500 can be any type of device described above as being usable with wireless nodes 102, which may include, but is not limited to, devices such as a product display assembly, a lock, a power outlet, a power strip, a display shelf, a display hook, and/or a docking station.
